Assembly and operation of the Juno's Spiner

The parts of the Juno's Spiner are in the left.

There are 12 outer elements (clear), 20 inner elements and 60 sets of rotational joints.

Pile up the element of two sheets and join together by rotational joint.

A clear element should always be placed outside of model.

Assemble them in the state of being easy to hold elements.

Check whether an element moves smoothly.

A clear element is in front of a blue element.

Add an element in the same way.

This photograph shows combined four sheets of elements. Please direct your attention that four elements are forming one loop.

You may understand the principle of transformation by operating a small number of element..

Always be conscious of making a loop with four sheets of elements.

Four elements are surrounding a circle.

If model is extended, it turns out easily which next should be connected.

If you move model little bit, it tends to become flat automatically.

Assemble model where it extended as much as possible.

Look for the place where one loop will be formed if one element is added. Then, assemble this part you found.

We had assembled half of the model.

Don't get the top and bottom of elements mixed up.

Almost finished.

Finished.

When you shrink Juno's Spinner, bounce it in your hands gently.

If you made mistake at top and bottom of elements, you wouldn't shrink it.

When you expand Juno's Spinner, hold opposite sides of outer elements.

Move your each hands away.

Twist your hands leave rotation of elements.

Left picture shows completely expanded Juno's Spinner.

You can expand Juno's Spinner make use of centrifugal force too.
